I’m finally the owner of iPhone 5s and I’m using it with VoiceOver. I know the system quite well though I can’t cope with one difficulty. Please give me a hint how to increase the volume of message alert. I do the following: tap the settings, select sounds, adjust the volume to 100% and mark the option that volume keys do not affect sound volume level. As a result, the sound of incoming call is extremely loud but the alert for text message is not that loud. So please help me in this matter. Many thanks!
